Question

我在我的（主要活动）中创建了一个Button（1）当我点击按钮（1）时会发生什么，它会显示一个包含自定义ListView的AlertDialog（1）。在那个Custom ListView中有一个Button，当点击它时它也会显示一个AlertDialog（2）并且它包含一个ImageView（Clickable）。我想要做的是如何将图像设置为我的ImageView。这是我的代码：

MainActivity.java - 这是我按钮的OnClick（1）

public void PayInvoice(View view){
    String minAmount = null;

    myDbHelper = new DBHelper(this);
    try {
        myDbHelper.createDataBase();
        myDbHelper.openDataBase();
        CustomerID = "1600050";

        minAmount = myDbHelper.getMinAmountDue(CustomerID);
    } catch (Exception e) {
        e.getMessage();
    }
    myDbHelper.close();

    if (TotalAmountET.getText().equals("") || TotalAmountET.getText().length() == 0) {
        Toast.makeText(this, "PUT PAYMENT AMOUNT FIRST...", Toast.LENGTH_SHORT).show();
    } else if (Float.parseFloat(minAmount) > Float.parseFloat(TotalAmountET.getText().toString()) ) {
        Toast.makeText(this, "TOTAL AMOUNT IS NOT ENOUGH...", Toast.LENGTH_SHORT).show();
    } else {
        AlertDialog.Builder alertdialogbuilder = new AlertDialog.Builder(PaymentHeader.this);
        LayoutInflater inflater = getLayoutInflater();
        View alertLayout = inflater.inflate(R.layout.sales_invoice_list, null);
        alertdialogbuilder.setView(alertLayout);

        final ListView SalesInvoiceList = (ListView) alertLayout.findViewById(R.id.invoiceList);
        final Button Cancel = (Button) alertLayout.findViewById(R.id.cancelBTN);
        final Button PayInvoice = (Button) alertLayout.findViewById(R.id.payinvoiceBTN);

        final AlertDialog alertDialog = alertdialogbuilder.create();
        alertDialog.setCanceledOnTouchOutside(false);
        alertDialog.show();

        myDbHelper = new DBHelper(this);
        try {
            myDbHelper.createDataBase();
            myDbHelper.openDataBase();

            CustomerID = "1600050";

            try {
                invoiceLists = myDbHelper.retrieveInvoices(CustomerID);
                customListView_invoiceList = new CustomListView_InvoiceList
                        (this, invoiceLists,Float.parseFloat(TotalAmountET.getText().toString()));
                SalesInvoiceList.setAdapter(customListView_invoiceList);
            } catch (Exception e) {
                e.getMessage();
            }

        } catch (Exception e) {
            e.getMessage();
        }

        Cancel.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                alertDialog.dismiss();
            }
        });

        PayInvoice.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                insertPaymentLine();
            }
        });
    }
}

CustomListView_InvoiceList.java - 这是我如何在AlertDialog（1）中填充ListView。

public class CustomListView_InvoiceList extends BaseAdapter {
private Context mContext;
private List<InvoiceList> invoiceLists;
private Float TotalPaymentAmount;
DBHelper myDbHelper;
List DeductionType;
private ArrayAdapter<String> DeductionTypeAdapter;
private final int requestCode = 20;

public CustomListView_InvoiceList(Context mContext, List<InvoiceList> invoiceLists, Float totalPaymentAmount) {
    this.mContext = mContext;
    this.invoiceLists = invoiceLists;
    this.TotalPaymentAmount = totalPaymentAmount;
}

@Override
public int getCount() {
    return invoiceLists.size();
}

@Override
public Object getItem(int position) {
    return invoiceLists.get(position);
}

@Override
public long getItemId(int position) {
    return invoiceLists.get(position).getId();
}

public static class ViewHolder {
    CheckBox SelectInvoiceCB, PayFull, PayPartial;
    TextView SalesInvoiceNo, InvoiceDate, InvoiceAmount, DueDate;
    EditText TotalAmount;
    LinearLayout adddeductionBTN;
    ImageView CaptureForm;
}

@Override
public View getView(final int position, View view, ViewGroup viewGroup) {
    //View v = View.inflate(mContext, R.layout.sales_invoice_custom,null);
    final ViewHolder holder;

    if(view == null)
    {
        view = View.inflate(mContext, R.layout.sales_invoice_custom,null);
        holder = new ViewHolder();

        holder.SelectInvoiceCB = (CheckBox) view.findViewById(R.id.selectInvoiceCB);
        holder.SalesInvoiceNo = (TextView) view.findViewById(R.id.SINo);

        holder.PayFull.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
            @Override
            public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
                if (holder.PayFull.isChecked()){
                    holder.PayPartial.setChecked(false);
                }

            }
        });

        holder.PayPartial.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {

                }
            }
        });

        try {

                holder.TotalAmount.setText(holder.InvoiceAmount.getText().toString());

                TotalPaymentAmount = TotalPaymentAmount - Float.parseFloat(holder.InvoiceAmount.getText().toString());
            } else {
                if (TotalPaymentAmount < 1) {
                    holder.TotalAmount.setText("0.00");
                } else {
                    holder.SelectInvoiceCB.setChecked(true);
                    holder.PayPartial.setChecked(true);
                    holder.TotalAmount.setText(String.valueOf(TotalPaymentAmount));
                    TotalPaymentAmount = TotalPaymentAmount - Float.parseFloat(holder.InvoiceAmount.getText().toString());

根据您的要求创建自定义对话框类并实现界面按照这个例子对话框类代码

  public class AddFlightDialog extends Dialog {


    @Bind(R.id.edtTxtflightnumber)
    EditText edtTxtflightnumber;
    @Bind(R.id.btnAddComment)
    Button btnAddComment;
    @Bind(R.id.btnCancelComment)
    Button btnCancelComment;
    private Context mContext;
    FlightNumberListner flightNumberListner;

    @OnClick(R.id.btnAddComment)
    void btnAddComment() {

        flightNumberListner.addflightnumber(edtTxtflightnumber.getText().toString());

        dismiss();
    }

    @OnClick(R.id.btnCancelComment)
    void closeDialog() {

        flightNumberListner.noflightNumber();
        dismiss();
    }

    String comment = "";

    public AddFlightDialog(String comment, Context context, FlightNumberListner flightNumberListner) {
        super(context, R.style.Theme_Custom);
        this.flightNumberListner = flightNumberListner;
        this.comment = comment;
        this.mContext = context;
    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.dialog_add_flight);
        ButterKnife.bind(CustomDialog.this);
    }

    public interface FlightNumberListner {
        public void addflightnumber(String flightnum);

        public void noflightNumber();
    }
}

对话调用方法

new AddFlightDialog(comment, getActivity(), new AddFlightDialog.FlightNumberListner() {
                @Override
                public void addflightnumber(String flightnum) {
                    //your code
                }

                @Override
                public void noflightNumber() {
                    //your code
                }
            }).show();

如何在myAdapter中的AlertDialog中创建的ImageView中设置图像？我使用Base Adapter
